I want to create a function typealias in the form:
typealias Handler = (@autoclosure condition: () -> Bool, @autoclosure _ message: () -> String, file: StaticString, line: UWord) -> ()
However, this is a compiler error.
Defining the func:
func f(@autoclosure condition: () -> Bool, @autoclosure _ message: () -> String, file: StaticString, line: UWord) -> (){ … }
This of course works.
Unless I just don’t understand something, it seems the typealias should be valid as well.
